Background:

Lecithin is regarded as a safe, conventional phospholipid source. Phospholipids are reported to alter the fatty acid composition and microstructure of the membranes in animal cells.

After culturing in MRS broth with 0.2 to 1.0% soy Lecithin, the survival rate of harvested cells increases significantly (P<0.05) in the 0.3% bile challenge compare with the no added soy Lecithin group. The cells incubated with 0.6% soy Lecithin are able to grow in an MRS broth with a higher bile salt content. The cell surface hydrophobicity is enhanced and the membrane integrity in the bile challenge increases after culturing with soy Lecithin. A shift in the fatty acid composition is also observed, illustrating the cell membrane changes in the soy Lecithin culture[1].
